Fact checkers seek lies in US election

A handful of online fact checking organisations are attempting to keep the presidential candidates honest by researching any suspicious statements made by either campaign. But a handful of groups have sprung up, claiming the fact checkers side with one party or the other.

FactCheck.org and Politifact.com are two outfits that have spent the past several years keeping tabs on politicians by fact-checking what they say at rallies, debates and conventions.

Though the websites have grown in popularity since they emerged in 2004 and 2007 respectively, other organisations claim their factual corrections are going unnoticed or that the websites are politically one-sided.
